Debug.Write not working

For some reason, the Debug class suddenly stopped working for me.

public void WhyDebugIsNotWorking()
{
     Debug.Write("Why am I not working !!!!!!");
}

On the above line, Debug.Write gets dim (I think Resharper is dimming it) and when I put the cursor on it, it says:

Method invocation is skipped. Compiler will not generate method invocation because the method is conditional, or it is a partial method without implementation.

None of the above conditions are true in my case. As you can see it's a very simple case. I'm not able to use Debug class at all. Please help!
